Don't forget to factor in the wind. Yesterday was overcast all day here in the Chicago area with temps 28-31 degrees for my entire 43 mile ride but there was virtually no wind. Today is much warmer, in the upper 30's with full sunshine. But there is a very brisk wind from the south which makes today feel colder than yesterday. I did a short hike with my husband at the arboretum today and was glad that I picked yesterday for my ride.
